T. R. HERBE S'I: ET AL METALLIC EDGING Filed April 12, 1928 Patented Sept. 23, 1930 UNITED STATES PATENT OFFICE THOMAS R. HERBEST AND CHARLES J. HOFFMAN, OF WHEEIJING, VIEST VIRGINIA, ASSIGNORS TO THE CONSOLIDATED EXPANDED METAL GOIVIPANIES,OF WHEELING, WEST VIRGINIA, A CORPORATION OF -W'EST VIRGINIA METALLIC EDGING Application filed April 12, 1928. Serial No. 269,396.

This invention relates to metallic edging, such, for example, as is useful for sashing for screens, gratings, guards, grilles, and the like, especially where material such as metallic fabric or lath is employed.

One of the primary objects of the invention is to provide a standard form of edging which is capable of a wide variety of applications.

Another object of the invention is to provide edging which affords maximum rigidity and strength with a minimum weight of metal.

Other objects and advantages will appear in the accompanying description of the preferred form of our invention which is illustrated in the drawings, wherein- Fig. 1 is a diagrammatic side elevation of a screen employing our invention, and

Figs. 2 to 11 inclusive are fragmentary cross sectional views illustrating a number of different ways in which the invention may be applied.

Referring now to Fig. 1, the reference numeral 7 may be taken as representing a frame such as a window frame, and the reference character A denotes the screen or similar member to be mounted in said frame.

The screen comprises a frame or sash con structed from the edging to be described and the metal fabric 8.

The edging employed in constructing the screen frame is shown in Figs. 2 to 11 inclusive, and is made from sheet metal pressed into substantially U-form in cross section, the legs 9 of the U being spaced sufficiently closely together to just about receive the particular type of metal fabric that is employed. The base of the edging is in the form of a bulb 10 in cross section. Four lengths of the edging are employed, the frame being completed by the brackets 11 at the corners.

It will be seen that the cross sectional form of the edging is one which is calculated to secure maximum strength and rigidity with a minimum weight of metal. The provision of the bulb also secures a number of other advantages, one of the most important of which is that the hinges or other means employed in fastening the screen frame may be attached to the screen frame in a number frames together. Fig. i shows one way in which two adjacent screen frames may be hinged together. Fig. 5 illustrates another way, while in Fig. 6 there is illustrated a way of hinging two screen frames together where the screens normally extend at right angles to one another. Another way of hinging two screen frames is illustrated in Fig. Swherein there is attached to the bulb portion of the adjacent frames a clip 13, one leg of which is rounded to engage the bulb, and the other leg of which is straight. A hinge 14: has its leaves secured to straight legs 13 of the respective clips. i

In Figs. 7'and 9 we have illustrated how clips 13 may be employed to secure screen frames together, either where the screens extend in the same plane or extend in planes at right angles te one another.- v

In Figs. 10 and 11 we have illustrated different ways in which the clips 13 may be employed to secure thescreen frames to the main frames,

We prefer to secure the leaves or legs of the edging to the bulb by. means of hard ened metal screws 15. To this end we drill holes in the bulb portion of the edging at appropriate places, these holes being of slightly smaller diameter than the screw, in consequence of which the screw taps its own thread in the bulb.

It will be seen from the foregoing that a relatively small number of standard attachtogether. In order to permit excess spelter to run out of the edging, holes 16 are provided in the brackets 11. In the absence of such holes, the edging may become solidly 5 filled with spelter which would be uneconomical and also result in excess in weight which would be objectionable. Where the screen or guard is not tobe galvanized, screws 15 may be employed to secure. the fabric between the legs of the edging.

We claim l. A screen comprising a frame, metallic fabric secured to the frame, said frame being composed of U-shaped metallic edging with the base in the form of a cylindrical bulb in cross section, and attaching means comprising a two-winged member, one Wing of which is adapted to be secured to an ad jacent structure, and the other wing being curved on the same radius as the bulb and having a width such that it is adapted to embrace approximately one-half of the bulb circumferentially, and means for securing said curved wing member to the bulb portion.

2. A screen comprising a frame, metallic fabric secured to the frame, said frame being composed of U-shaped metallic edging with the base in the form of a cylindrical bulb in cross section, and attaching means engaging the bulb comprising a two-winged hinged member, each of the wings'of which is curved on the same radius as the bulb and having a width such that each is adapted to embrace about'half of a bulb circumferentially, and means for securing the said two wings to bulb portions.

3. A screen comprising a frame, metallic fabric secured to the frame, said frame be- 40 ing composed of U-shaped metallic edging, with the base in the form of a cylindrical bulb in cross section, and attaching means comprising a two-winged member, each wing of which is curved on the same radius 5 as the bulb and having a width such thatit is adapted to embrace approximately half of the bulb circumferentially, and means for securing said wings to bulb portions.

In testimony whereof We have hereunto signed our names.
